Volume setting on Xiaomi Redmi: from basic parameters to hidden features

Xiaomi Redmi smartphones are known for their balance of price and quality, but sometimes users face the problem of too quiet sound or uneven volume in the speakers. The reasons can vary from incorrect settings to hardware limitations of a particular model. This article will help you understand how to increase the volume on Redmi, adjust the sound to your preferences and eliminate typical audio problems.

We'll look at both standard modes of adjustment through the system menu and the hidden features available through the engineering menu, and we'll focus on stereo models like the Redmi Note 10 Pro or Redmi K50, where it's important to balance left and right channels correctly. If the sound is quiet after all the manipulations, at the end of the article you'll find a checklist for hardware malfunctions.

1. Basic volume setting through notification curtain

The easiest way to adjust the volume is to use a slider in the Quick Settings Panel, which works on all Redmi models, from the budget (Redmi 9A) to the flagship (Redmi K60 Ultra).

• 📱 Unlock the screen and swipe from top to bottom to open the notification curtain.
• 🔊 Find the volume slider (usually located to the right of the speaker icon).
• 🎵 Click on the arrow next to the slider to deploy the advanced sound settings.
• 🔄 Here you can separately adjust the volume for media, calls, alarm and notifications.

Note that on some models (for example, Redmi Note 12), when you click on the speaker icon in the curtain, the Sound and Vibration menu immediately opens. If the slider does not respond to touch, check if the Do Not Disturb mode is activated (the bell icon with cross-out).

2. Advanced sound settings in the parameters menu

If you don't have enough basic adjustment, go to the full audio settings menu, and you can adjust not only the volume, but also the sound quality, the balance of stereo speakers, and even turn on low frequency amplification.

1. Open Settings (the gear icon on the main screen).
2. Go to the section Sound and vibration.
3. In the Loudness block, adjust the sliders for each type of sound: 🎶 Media - music, video, games; 📞 Call – the volume of incoming calls; ⏰ Alarm clock – the sound of the alarm clock; 🔔 Notifications - Alerts from Applications.

Change the volume with the buttons

On models with MIUI 14 and later, the Sound Effects section appeared on the same menu.

• 🎧 Boosting bass (useful for listening to music);
• 🔊 Expansion of stereobase (for a larger sound);
• 🎵 Equalizer (frequency settings for music genres).

💡

If after the MIUI update the equalizer settings have disappeared, try resetting the Music application settings in the Settings menu → Applications → Application Management.

Setting up the balance of stereo speakers (for models with two speakers)

Redmi models with stereo sound (such as the Redmi Note 11 Pro+ or Redmi K50 Gaming) sometimes suffer from a volume imbalance between the top and bottom speakers, which can be due to both software settings and physical clogging of one of the speakers, to adjust the balance:

1. Open Settings → Sound and vibration → Balance of stereo speakers.
2. Move the slider left or right to equalize the volume.
3. To check, play the test sound (for example, on YouTube, turn on a video with stereo effects).

On models with Dolby Atmos support (such as the Redmi K50 Pro), the speaker balance can be reset once this mode is turned on/off. To avoid a problem, turn off Dolby Atmos in the sound settings before adjusting the balance.

4.Use of engineering menu to increase volume

If the standard settings are not loud enough, you can use the engineering menu (MTK Engineering Mode or Qualcomm Diag, depending on the processor).This method requires caution, since incorrect changes can lead to failures.

1. Open the Phone app and enter the combination: ##36446337###
2. Go to the Hardware Testing → Audio section.
3. Select LoudSpeaker Mode (or Speaker).
4. In the Value field, increase the value to 150 (max 160, but this can cause distortion).
5. Press Set, then restart the phone.

For smartphones on Qualcomm Snapdragon (for example, Redmi Note 12 Pro+):

1. Enter the phone app: ##4636##
2. Go to Audio → Speaker Gain.
3. Increase your Media and Ring values by 2-3 points (no more!).

⚠️ Attention: Increased volume through the engineering menu can cause distortion of the sound at maximum levels or even damage to the speakers during prolonged use.

Record the current parameter values|Do not increase the volume by more than 20% of the standard|Check the sound at a medium level before saving|Make a backup copy of the data-->

5. Checking speakers for hardware malfunctions

If after all the manipulations, the sound remains quiet or distorted, the problem may be hardware.

• 🔍 Visual inspection: Light a flashlight into the speaker's grille - if dust or debris is visible, gently clean it with a soft brush.
• 🎧 Headphone test: Put your headphones on and check the volume. If they sound normal, the problem is with your phone's dynamics.
• 🔊 Microphone check: Record a voice message. If your voice sounds quiet or jammed, the microphone may be clogged (it is often located next to the speaker).
• 📱 Test in Safe Mode: Reboot your phone in Safe Mode (click the power button) → Safe Mode. If the sound is normal, it's the third-party app's fault.

Typical hardware problems:

• 🛠️ Splitting contacts speaker (often after a phone drop);
• 💦 Moisture infestation (even if the phone hasn’t sunk, condensation can oxidize contacts);
• 🔋 Wear speaker (typical for phones older than 3 years).

6. Software solutions: applications for amplifying sound

If there are no hardware problems, but the volume is still not enough, you can use third-party applications.

How to install and configure Volume Booster:

1. Download the app from Google Play.
2. Launch and give access to the sound settings.
3. Move the Booster Level slider 30-50% (more is the risk of distortion).
4. Enable the Auto Boost for Media option.

⚠️ Warning: Sound amplification applications can drain the battery faster and overload the processor. Don't use them all the time - only when necessary (e.g., to watch a movie in a noisy place).

7. Resetting the sound settings to factory

If you have problems with the sound after the experiments (for example, the volume control is lost or the sound is intermittent), resetting will help, which will return all parameters to factory values without deleting personal data:

1. Open the Settings. → The phone.
2. Click on Settings Reset.
3. Select Reset sound and vibration settings.
4. Confirm the action and restart the phone.

After discharge:

• 🔄 Check the base volume in the notification curtain;
• 🎵 Reset the equalizer (if used);
• 🔊 Make sure you're in the Settings → Special Options Disabled Monoaudio Mode.

💡

Resetting audio settings does not delete your files or applications, but returns to factory settings all changes made through engineering menus or third-party utilities.
